A new IMF report on New Zealand says that “New Zealand’s mainly LVR-related housing market-specific macroprudential measures would appear to have had some moderating influence on mortgage lending, expected and actual house price growth, and the quality of loan composition. In addition, they have also helped to contain household leverage. However, they do not seem to have prevented a continuous deterioration of borrower households’ vulnerability against debt servicing capacity risks, such as higher interest rates or income shocks.”

Also, see a separate IMF report on New Zealand’s financial sector, which also discusses the housing market.
